Advantages |
Single Path
Light Beam Switch |
Light
from transmitter to receiver only travels one way. This means
extended operating range and high function reserves. Objects
interrupting the light beam initiate a switching process. |
- Reliable operation even in
harsh environmental conditions.
- Well reproduced switching point
- Trouble free detection of reflective,
opaque objects
|
Reflection Light Beam Switch |
Light
from the transmitter is reflected back into the receiver. Objects
interrupting the light beam initiate a switching process. |
- Fitting and electrical connections
for only one device
- Reflectors available for every
type of application
|
Reflection
Light Beam Switch with Polarization
Filter |
The
receiver only registers light transmitted from the triple reflector
as it has a relative effect on the light polarization. Therefore
shiny objects which also act as reflectors, but do not affect polarization,
can be reliably detected. |
- Reliable interruption of light
beam with shiny and reflective objects
|
Reflection
Light Scanner |
Any
object within scanning range initiates the switching process. The
scanning range largely depends on the reflection value of the object
to be detected. |
- No reflector necessary as the
object itself acts as reflector
|
Background Suppression Scanner |
The
receiver determines whether the transmitted light it receives is
reflected from an object within or outside (i.e. in the background)
the scanning field. |
- Almost
constant scanning range for diffuse reflecting objects with greatly
varying reflecting value
- Also dark objects can be reliably
detected on a light background
- Not sensitive to intrusive
reflections from objects in the background
- Very high function reserve
